Small-scale fish farming in seasonal ponds in Brazil: technical and economic characterization

ABSTRACT The inclusion of aquaculture in household agriculture has been related as an opportunity of product and income diversification as wells as to increase food security for farmers. Small-scale fish production has increased in Brazil, even in regions with a pronounced dry season. However, there...
